Okwangoku, ukunqongophala kombane kwihlabathi kuya kusiba mbi ngakumbi. Iinkampani ezininzi kunye nabantu ngabanye bakhetha ukuthenga iiseti zejeneretha ukunciphisa izithintelo kwimveliso kunye nobomi obubangelwa kukungabikho kwamandla. I-AC alternator yenye yecandelo elibalulekileyo kwiseti yejenereyitha epheleleyo. Indlela yokukhetha ii-alternators ezithembekileyo, ezi ngcebiso zilandelayo kufuneka ziqatshelwe:
I. Iimpawu zoMbane:
1. Inkqubo ye-excitation: Ngeli nqanaba, inkqubo yokuvuselela i-alternator ye-AC yezinga eliphezulu i-self-excitation, ngokuqhelekileyo ixhotyiswe nge-automatic voltage regulator (AVR). Amandla okukhutshwa kwe-rotor ye-exciter idluliselwa kwi-rotor yomkhosi ngokusebenzisa i-rectifier. Izinga lohlengahlengiso lwe-voltage ezinzileyo ye-AVR ubukhulu becala ≤1%. Phakathi kwazo, i-AVR ekumgangatho ophezulu inemisebenzi emininzi efana nokusebenza ngokuhambelanayo, ukukhuselwa kwamaza aphantsi, kunye nohlengahlengiso lwangaphandle lombane.
2. I-Insulation kunye ne-varnishing: Ibakala lokugquma kwee-alternators ezisemgangathweni ngokuqhelekileyo liklasi "H", kwaye zonke iindawo zalo ezijikelezayo zenziwe ngezinto eziphuhliswe ngokukodwa kwaye zifakwe kwinkqubo ekhethekileyo. I-alternator iqhuba kwiindawo ezinzima ukubonelela ngokhuseleko.
3. Umoya kunye nokusebenza kombane: I-stator ye-alternator ephezulu iya kuhlanjululwa ngamacwecwe ensimbi epholileyo kunye ne-magnetic permeability ephezulu, i-wind-stacked windings, isakhiwo esinamandla kunye nokusebenza kakuhle kwe-insulation.
4. Ukuphazamiseka kwefowuni: I-THF (njengoko ichazwe yi-BS EN 600 34-1) ingaphantsi kwe-2%. I-TIF (njengoko ichazwa yi-NEMA MG1-22) ingaphantsi kwama-50
5. Ukuphazamiseka kweRadio: Izixhobo eziphezulu ze-brushless kunye ne-AVR ziya kuqinisekisa ukuba kukho ukuphazamiseka okuncinci ngexesha lokusasazwa kwerediyo. Ukuba kuyimfuneko, isixhobo esongezelelweyo se-RFI sokunciphisa sinokufakwa.
II. Iimpawu zoomatshini:
Umgangatho wokhuseleko: Iindidi ezisemgangathweni zazo zonke iijenereyitha zomhlaba ze-AC yi-IP21, IP22 kunye ne-IP23 (NEMA1). Ukuba kukho imfuneko yokhuseleko ephezulu, ungakhetha ukunyusa umgangatho wokhuseleko we-IP23. Uhlobo olusemgangathweni lwejenereyitha ye-AC yaselwandle yi-IP23, IP44, IP54. Ukuba ufuna ukuphucula umgangatho wokukhusela, njengokusingqongileyo kunxweme lolwandle, unokuxhobisa i-generator ye-AC kunye nezinye izixhobo, ezifana nezifudumezi zendawo, izihlungi zomoya, njl.
Ukunqongophala kwamandla ehlabathi kukunyuse kakhulu ukuthengiswa kwe-AC alternator/ jenereyitha. Amaxabiso ezincedisi ze-AC generator ezifana ne-disc couplings kunye ne-rotors zinyukile kwibhodi yonke. Unikezelo luqinile. Ukuba ufuna umbane, ungathenga iijenereyitha ze-AC ngokukhawuleza. Ixabiso lejeneretha ze-AC likwanyuka rhoqo!
